Sleep-related problems (SRPs) are common and problematic among anxious youth but have not been investigated in anxious youth with autism spectrum disorder (ASD). Participants were 102 youth (ages 7-16 years) with ASD and comorbid anxiety. Youth and their primary caregiver were administered the Pediatric Anxiety Rating Scale. Parents completed the Multidimensional Anxiety Scale for Children-Parent (MASC-P) Report, Social Responsiveness Scale, and the Child Behavior Checklist (CBCL). A measure of SRPs was created from items from the CBCL and MASC-P. Results suggest SRPs were relatively common among youth with ASD and comorbid anxiety. The number of SRPs endorsed directly associated with parent ratings of social deficits, internalizing and externalizing symptoms, and anxiety symptoms, as well as with clinician-rated anxiety symptoms. Parent-rated internalizing symptoms predicted frequency of SRPs over and above social deficits, externalizing symptoms, and parent- and clinician-rated anxiety symptoms. A subset of 40 participants who completed family-based cognitive-behavioral therapy (CBT) experienced reduced SRPs following treatment. Implications, study limitations, and recommendations for future research are discussed.

Anxiety symptoms are common in youth with autism spectrum disorders (ASD) and directly associated with symptom severity and functional impairment. Family accommodation occurs frequently among individuals with obsessive-compulsive and anxiety disorders; to date, no data exist on the nature and correlates of family accommodation in youth with ASD and anxiety, as well as its relationship to cognitive-behavioral therapy outcome. Forty children with ASD and a comorbid anxiety disorder participated. Clinicians administered measures of ASD and anxiety disorder caseness, anxiety symptom severity, and family accommodation; parents completed questionnaires assessing social responsiveness, internalizing and externalizing behaviors, and functional impairment. A subsample of youth (n = 24) completed a course of cognitive-behavioral therapy. Family accommodation was common and positively correlated with anxiety symptom severity, but not functional impairment, general internalizing symptoms, externalizing behavior, or social responsiveness. Family accommodation decreased following cognitive-behavioral therapy with decreases in family accommodation being associated with decreases in anxiety levels. Treatment responders reported lower family accommodation frequency and lower parent impact relative to non-responders. Clinical implications of this study in assessing and psychotherapeutically treating youth with ASD and comorbid anxiety are discussed., (Copyright © 2015 Elsevier Ltd. All rights reserved.)

Objective: Examine the efficacy of a personalized, modular cognitive-behavioral therapy (CBT) protocol among early adolescents with high-functioning autism spectrum disorders (ASDs) and co-occurring anxiety relative to treatment as usual (TAU)., Method: Thirty-one children (11-16 years) with ASD and clinically significant anxiety were randomly assigned to receive 16 weekly CBT sessions or an equivalent duration of TAU. Participants were assessed by blinded raters at screening, posttreatment, and 1-month follow-up., Results: Youth randomized to CBT demonstrated superior improvement across primary outcomes relative to those receiving TAU. Eleven of 16 adolescents randomized to CBT were treatment responders, versus 4 of 15 in the TAU condition. Gains were maintained at 1-month follow-up for CBT responders., Conclusions: These data extend findings of the promising effects of CBT in anxious youth with ASD to early adolescents., (© 2014 Wiley Periodicals, Inc.)
